GlasSpec2500

Specified visible and NIR spectral measurement instrument for architectural glass.

GlasSpec2500 is specially designed for glass visible and NIR spectrum measurement for glass manufactures and quality inspection institutions. The instrument not only can measure the optical parameters of single pane, but also can directly measure IG without separating. It can measure the overall solar direct spectrum transmittance and reflectance. With special software function, we can directly obtain optical performance of energy-saving glass.
